A common issue in personal injury orthopaedic cases is whether the damage of which the claimant complains is degenerative or traumatic in origin or a combination. This case illustrates for specialists in neurosurgery, orthopaedics, pain medicine and radiology how the court resolved conflicting expert evidence. It also illustrates the risks of reliance on the claimant’s self-reported history, especially if they have taken it upon themselves to research into areas of medical and legal expertise.

Rezmuves v Birney [2024] IEHC 592 

The judge in this claim for professional negligence struck out a witness statement which contained paragraphs which were pure opinion, made by the witness as a self-proclaimed expert, noting that it was expert evidence by the back door, in contravention of CPR Part 35 and plainly abusive. 

Israel Russell v Barry Coulter [2025] EWHC 493 (KB)

This is a case in which the tribunal was critical of an expert witness. One criticism was that he did not expressly acknowledge the guidance provided in the Ikarian Reefer in his declaration – “a step taken by many experts who prepare reports for this Chamber”.

While the Judge in this extradition appeal ultimately reached the same conclusion as the District Court Judge, and dismissed the appeal, he pointed out significant deficiencies in how the District Court Judge had treated the expert psychological evidence.

This case illustrates how the Family Court depends on expert paediatric and radiological evidence to decide when and how a child’s fracture was sustained. This summary does not include how the court used the evidence. Suffice it to say that the expert evidence was only a part of the evidence before the court.  

C1 and C2 (Children: Fact Finding), Re [2024] EWFC 247 (B)

The judge preferred the evidence of the Claimant's expert because of the Defendant's expert’s approach to his task as expert, his confusion over the proper approach to what prior art was and was not in the common general knowledge, the number of assertions he made which he was forced to resile from as incorrect, and his failure to acknowledge a key fact.

The issue in this judicial review did not turn on the expert evidence but the case illustrates the role of a medical reporting organisation (MRO) in a particular civil case and there are some general learning points.

Of note, the MRO did not arrange the correction of an erroneous date, it did not recognise how the evidence set out by the expert was seemingly insufficiently referenced and it did not recognise that there would be questions as to how some of the expert’s conclusions were reached.

Ivory, R (On the Application Of) v Welwyn Hatfield Borough Council [2025] EWCA Civ 21

The judge found that the forensic accounting expert’s approach of forming an opinion as to the value of the Company, then carrying out a detailed calculation and only if it matches his initial opinion accepting it, undermined the credibility and reliability of his opinion as to the value of the Company.

This is a case which will assume much greater importance for the 15 points of practice and practical steps that the judge decided can help reduce the risk of well-meaning professionals falling into pitfalls that hinder the identification of safeguarding issues at an early stage than as a case with learning points for experts.

For some of the experts in the fields from which jointly appointed experts were instructed, it illustrates how their evidence is tested and applied in a case of suspected fabricated or induced illness (FII).

Re N (Children: Fact Finding - Perplexing Presentation/Fabricated or Induced Illness) [2024] EWFC 326

Any uncertainty as to whether a psychiatrist can provide an expert report as a paper-based assessment is answered by this case.

In this case the paper-based assessment was sufficient for the court to conclude that, having regard to the Mental Capacity Act 2005, s 48, there were "reasons to believe that the Appellant lacks capacity". However, the fact that the court did not make a finding of a lack of capacity and transferred the case to a Tier 3 (High Court) Judge of the Court of Protection in order to determine the matter of capacity indicates how the court recognises how much more difficult it is to make a finding when the report relies on a paper-based assessment compared to a consultation with the subject of the report.
